| Abstract: | High entropy alloys (HEAs) are new generation of alloys which have been developed rapidly in recent years. The composition design of HEAs is a breakthrough of the traditional alloy design idea, and it is a new developing direction of alloy theories. With the high entropy effect, severe lattice distortion effect, sluggish diffusion effect and cocktail effect, the HEAs have promising applications in welding fields. This paper summarized the research status and existing problems in developing the welding filler materials and welding processes utilizing the four effects of HEAs, and the trend of development is prospected as well. |
